How to exclude data from Writeline

I am using writeline to write out data from a server it is a list of blacklisted IP addresses. But I only want the addresses that are denied not the one that are allowed anyone can you help me get this right here is the code. The allowed flag is something I can access from the COMAPI.

WriteStuff.WriteLine ("AutoBan," & CStr(key2.address) & "," & CStr(key2.banned) & "," & CStr(key2.permanently) & "," & CStr(key2.expires) & "," & CStr(key2.reason))
